"Every healing effect I've seen involves some combination of positive energy and detail-focused repairs to the structure of something. Your Deliverance, I believe that this has worked when you've tried it before. I believe there's a decent chance it would work on me, and if I'm too busy dying to communicate and using my Cure wand on me won't cut it, it's a reasonable thing to try."

"But I need to emphasize that from my perspective, any god local to this region is an outer god. The last time an outer god used an effect on my party which seemed to just evoke eir domain directly, it almost killed multiple of us, even though eir domain didn't sound like it would do that."

She grits her teeth. It may somehow have escaped Griffie that she is very important and busy and there is not much slack in her day. 

- Is she possibly just frustrated by having just come out from the extremely long and arduous Vigil and learning that the state of the Far Realms is probably worse than they thought, why yes she is, is that a good reason to act all angry, no it is not. 

She wouldn't trust a foreign god either. In fairness, she would be right not to do that and Griffie isn't, but still.

"I understand. Would you like to see me heal someone, for reassurance? Do you have similar senses for that as you do for souls?"

"Sure. I'm … also quite willing to leave you alone, it is just that you seemed to want to persuade me. I don't mean to disrupt your schedule."

"I do want to persuade you, and also - you are a visitor from the Far Realms, this is important." And she still might have to destroy Axis, and if she does then time is precious. "I am almost always under time pressure, this is not new."

"How about I draw the diagrams I wanted to show you and you have someone let me know when you next plan to use the relevant healing effect. I'd also be happy to demonstrate the familiar sort of healing to one of your assistants."

"I would like to see the diagrams, yes. ...The sort of healing I had in mind for you usually has people on a waiting list for it. We may as well shorten the queue a little." Especially because it is actually important to know what the hell is going on with Griffie's 'soul', what it's actually like for all the prisoners of Axis, and how they can go about fixing it.

She's hoping that what Griffie is calling a 'soul' is some kind of complex curse Charon cooked up that specifically deceives and confounds the actual soul, in which case regeneration should just pop it like a bubble. 

"...And I think in fact I had better watch this 'healing' personally."

Probably Necromancy and almost definitely magic from the Far Realms, so better that she be there to intervene.

"Your Deliverance, the simplest healing spell I have on hand, the one I can cast all day, is called Stabilize. Its intended purpose is to make a dying creature stop slipping further into death. If I cast it on myself right now, it will do nothing, but you might still be able to see it. If you want to see it in action, I could give myself an extremely shallow cut first. I don't think we should test it on anyone from here without more information."

She turns her greater sight on em. "Please do. On both counts."

...And ready her own healing, in case this is in fact as mad as it sounds, which is doubtful but would make sense of all this.

Griffie doesn't have an immortal soul of the local sort. Ey has something intangible made of some sort of energy attached with a stem to around where eir brainstem probably is. There's a complex core piece, and some simpler pieces glued onto it.

Something deeply embedded in the pieces is slowly degrading them. You could compare it to it burning or corrosion, if you wanted. The system is arranged such that the simpler pieces are taking the brunt of the damage.

"I'm going to cast Stabilize in three, two, one…"

Griffie casts a 0-circle Conjuration (healing) spell with no material or focus components, targeting emself. This conjures a very small blob of energy, which Griffie's body absorbs and does basically nothing with.

"Now I'm going to give myself a shallow cut."

Griffie draws a small scimitar and does so, then puts it away again.

"And I'll cast Stabilize again in three, two, one…"

Griffie casts the same spell with the same target. This conjures a very small blob of energy, which Griffie's body absorbs. The wound mostly closes.

 - All right, to her senses Griffie looks bizarre but... this is not totally incompatible with eir 'soul' in fact just being a complicated curse. Actual souls aren't the kind of thing that has substance. 

...The possibility that Griffie is right has to be acknowledged and is deeply, metaphysically terrifying. Fuck.

Maybe that really is it. Maybe there is no Griffie in the cosmic sense, somehow, just a weird pattern of energy and flesh - how does that even make sense - what, would Mordenkainen's Disjunction just utterly and permanently destroy anyone from Griffie's world? Something will have gone badly wrong if that ever comes up, apparently she is just pointlessly generating worst-case-scenarios now. The swamp does make her like that. She stops it. 

On the positive side, healing corrosion seems eminently doable, as does doing something about the pieces. ...Sirenna's Name would do it but has the disadvantage of probably also destroying Griffie. ...She was already doing this, obviously, but it is extremely important to keep Griffie very far away from any sort of magical danger, good gods it's like ey're going around with glass bones but so much worse. 

Or maybe there is some kind of trick going on. 

Heaven will still make it right in the end, somehow. 

Well, it doesn't look like any kind of Necromancy she's ever seen. It mostly just looks like some kind of blob of Mysterious Immaterial Fluid. Why.

...She heals herself, just in case she's hallucinating all this under the stress. She is not. She should still talk to a confessor in case somehow she's erring more subtly or only imagined healing herself, but too far down that path lies madness. 

"Thank you. That is indeed... very different from anything I would have imagined."

"You're welcome. I hope this helps you understand my concerns."

She pinches the bridge of her nose. "I have never heard of a case of healing doing any harm. I would have expected it to be impossible."

"What are the strangest cases of healing you've heard of?"
